Thanks guys, I was wondering about MEK I've used it for other applications but was a bit nervous when it came to this stock. The last thing I need to do is apply something that will hurt it.

I took the suggestion of applying some heat. I put it under a heat lamp and the oil jumped to the surface. I'm going to wipe it down on a regular basis and hopefully get the oil out.

If someone has other suggestion's, I'm all ear's!
